Aneurisma IV: Manejo de enfermería
La monitorización rigurosa para detectar la rotura del aneurisma es esencial en pacientes sometidos a cirugía aórtica.
Manejo preoperatorio de enferme…
Los cuidados de enfermería preoperatorios para pacientes sometidos a cirugía endovascular incluyen la evaluación periódica de los pulsos periféricos del paciente y el seguimiento de las manifestaciones de la rotura del aneurisma, como taquicardia, hipotensión, dolor en las áreas abdominal, inguinal, de espalda o periumbilical y una masa abdominal pulsátil.
Indique al paciente que consuma una dieta de líquidos claros el día antes de la cirugía y que permanezca sin recursos después de la medianoche antes de la cirugía.
Administre laxantes o enemas orales según lo prescrito y realice la limpieza de la piel con un agente antimicrobiano el día antes de la cirugía.
Proporcionar medicamentos recetados, como antibióticos.
Para el manejo postoperatorio de enfermería, coloque al paciente en decúbito supino durante 6 horas para reducir la presión en el sitio de punción arterial.
Monitorizar los signos vitales y realizar evaluaciones Doppler de los pulsos periféricos cada 15 minutos durante las primeras horas.
Evalúe el sitio de acceso en busca de sangrado, hematoma y áreas cianóticas de forma irregular.
Además, administre oxígeno, líquidos intravenosos, componentes sanguíneos y medicamentos según lo indicado.

Q1: What are the key signs of aneurysm rupture that nurses should monitor before surgery?
Nurses must continuously monitor for clinical manifestations and diagnostic indicators of rupture, including tachycardia, hypotension, pallor, weakness, abdominal or back pain, changes in consciousness, and a pulsating abdominal mass. Regular assessment of peripheral pulses is essential. Immediate reporting of these signs enables rapid intervention and prevents life-threatening complications.
Q2: How should patients be prepared the day before endovascular aneurysm surgery?
Preoperative preparation includes instructing patients to consume a clear liquid diet and remain NPO after midnight. Administer prescribed oral laxatives or enemas and perform skin cleansing with antimicrobial agents. Provide prescribed medications, including intravenous antibiotics. These measures reduce infection risk, prevent aspiration, and ensure optimal surgical conditions.
Q3: Why is patient positioning critical during the immediate postoperative period after aneurysm repair?
Positioning the patient supine for 6 hours reduces pressure on the arterial puncture site, typically the femoral artery, preventing bleeding and hematoma formation. After 2 hours, the head of the bed may be elevated up to 45 degrees. This positioning strategy protects the access site while maintaining hemodynamic stability during early recovery.
Q4: What postoperative assessments should nurses perform on peripheral pulses and access sites?
Nurses perform Doppler assessments of peripheral pulses every 15 minutes initially, assessing femoral, posterior tibial, popliteal, and dorsalis pedis pulses for descending aorta surgeries. Continuously monitor the access site for bleeding, hematoma, and irregularly shaped cyanotic areas indicating embolization. Report any changes in pulse quality, vital signs, swelling, pain, or pulsation immediately.
Q5: How do nurses monitor for postimplantation syndrome after aneurysm repair?
Postimplantation syndrome presents with spontaneous fever, leukocytosis, and transient thrombocytopenia. Nurses monitor laboratory results for elevated white blood cell counts and assess vital signs regularly. Understanding these expected inflammatory responses helps distinguish normal postoperative reactions from infection, guiding appropriate clinical decision-making and patient management.
Q6: What fluid and medication management strategies support postoperative aneurysm repair recovery?
Administer IV fluids, electrolytes, and blood components as ordered to maintain adequate blood flow. Monitor central venous pressure and urine output hourly to assess hydration and perfusion status. Provide prescribed diuretics, antihypertensive agents, analgesics, and antidysrhythmics. Maintain continuous ECG monitoring and oxygen therapy to enhance myocardial oxygen supply and prevent complications.
Q7: How should nurses manage nasogastric tubes and promote bowel function after aneurysm surgery?
Connect the NG tube to low, intermittent suction to decompress the stomach, prevent aspiration, and reduce pressure on suture lines. Record the amount and character of NG output. Assess bowel sounds every 4 hours and encourage early ambulation to restore bowel function. Six hours postoperatively, patients may roll side to side and ambulate with assistance.
